Definitions

  • the invention relates to a method for feeding Additives in a polymer melt stream, in which the A partial stream is taken from the polymer melt stream and this partial stream is also taken Additives is mixed and the partial flow mixed with the additives is supplied to the polymer melt stream again.
  • DE-PS 4039857 describes a method and an apparatus for direct, continuous modification of polymer melts described.
  • a main melt stream is optionally one modifying partial melt flow removed and into a Double-shaft extruder directed.
  • the additives pass through a Feed pump in the twin-screw extruder.
  • the modified Partial melt flow then becomes the main melt flow again fed.
  • EP-B-0 532 988 describes a method for producing statistical Copolyester described. According to a preferred embodiment it is provided that a polyester (B) and 10 to 50 wt .-% of a Polyester (A) are fed to a mixing extruder, and the extrudate then in a static mixer with the rest 90 to 50 wt .-% of the polyester (A) is mixed.
  • the invention has for its object a method for feeding of additives in a polymer melt stream in which a homogeneous premix of additives and some of the Polymer melt is reached. This should also be ensured if the additives have different rheological properties than that Have polymer melt.
  • the object underlying the invention is achieved in that the unmixed partial flow completely or in maximum (n-1) further Partial flows each directly to a maximum of (n-1) pump gears, a planetary gear pump with n pump gears is supplied, the Additives at the same time unmixed at least one Pump gear of the planetary gear pump can be fed directly with the Additives mixed partial flow in the middle of the inlet of the planetary gear pump discharged from the planetary gear pump and into the polymer melt stream is introduced.
  • the polymers used are, for example, polyesters, Polyamides, polyurethanes or polyolefins are used.
  • additives come for example heat and UV stabilizers, lubricants, Mixed polymers or color concentrates are used.
  • n is in the range of 2 to 10.
  • the amount of the partial stream usually comprises 2 to 10% of Polymer melt flow.
  • the partial flow mixed with the additives becomes dissipated at the inlet of the planetary gear pump, the planetary gear pump is thus against the usual flow direction from the exits operated towards the entrance. It has been surprisingly demonstrated that the additives are homogeneous at the outlet of the planetary gear pump the partial stream of the polymer melt stream are mixed well. It is it is possible to add various additives to the pump gears Feed planetary gear pump and in the divided partial flow of Introduce polymer melt stream homogeneously.
  • the partial flow mixed with the additives is then returned to the polymer melt stream. This can then be in passed in a particularly advantageous manner through a static mixer become.
  • the additives are mixed homogeneously with the partial flow distributed relatively quickly in the polymer melt stream homogeneously, which by the advantageous premixing of additives and the partial flow of Polymer melt flow is reached. Because of this premix it is also possible in an advantageous manner, the mixing section of the optionally arranged static mixer to choose relatively short.
  • a preferred embodiment of the invention is that n 3 to 8. This allows the homogeneous mixing in realize in a particularly advantageous manner even if several Additives are used, the design effort being relative is low.
  • the partial stream mixed with the additives after exiting the Planetary gear pump passed through a static mixer and then in introduced the polymer melt stream.
  • This measure will homogeneous mixing in a relatively simple way reinforces what is advantageous to the homogeneous introduction into the polymer melt stream affects.
  • the at least one unmixed at the same time Pump gear supplied additives in the planetary gear pump at Merge with the partial polymer streams centrally to the exit axis of the pump.
  • the homogeneous mixing takes place on this Way relatively quickly over a short distance.
  • the invention is based on the drawing (Fig.) And exemplified.
  • Fig. Shows a simplified, schematic process flow diagram of the Process for feeding additives into a polymer melt stream.
  • Fig. Is the method for feeding additives (4) in one Polymer melt flow (1) is shown schematically simplified.
  • the Polymer melt stream (1) a partial stream (2) is taken and in three further partial streams (2a, 2b, 2c) divided. Every further partial stream (2a, 2b, 2c) one pump gear (3a, 3b, 3c) each Planetary gear pump (3) supplied.
  • the planetary gear pump (3) has four Pump gears (3a, 3b, 3c, 3d).
  • the additives (4) are one Pump gear (3d) fed. It happens in the planetary gear pump (3) a homogeneous premixing of the additives (4) with the divided one Partial stream (2).
  • the partial stream (5) mixed with the additives is on Entry of the planetary gear pump (3) from the center of the planetary gear pump (3) dissipated and introduced into the polymer melt stream (1).
  • this is mixed with the additives Partial stream (5) passed through a static mixer (6), which is also has an advantageous effect on the homogeneous premix.
  • the Introducing the partial stream (5) mixed with the additives (4) into the Polymer melt flow (1) takes place via a nozzle (7). More static Mixers (8) enhance the homogeneous mixing of the with the additives mixed partial stream (5) in the polymer melt stream (1).
  • the Partial stream (2) can only be divided into two further partial streams (2a, 2b).
  • the divided partial stream (2) can advantageously be used simultaneously with two different additives (4) are mixed homogeneously (not shown).
